Social movement unionism in Spain's feminized precarious service sector: Criticism, cooperation and competition

‘Social movement unionism’ (SMU) has been suggested as a suitable strategy for union renewal in Spain, yet the literature on union renewal and SMU has two major shortcomings: (1) a lack of bottom‐up studies, and (2) a lack of dialogue between industrial relations and social movement research. To redress these shortcomings, we make three contributions in this article: first, we provide evidence on the current opportunities for SMU in Spain's feminized precarious service sector; second, we apply a bottom‐up intersectional approach to the study of SMU; and third, we bridge the research on industrial relations and on social movements by adopting a relational framework that looks at both union and non‐union actors as key actors for union renewal. Our results show a landscape of co‐existence, conflict, cooperation and competition between union and non‐union actors, including established unions, radical grassroots unions and emerging forms of collective representation; however, if we are to develop SMU as a strategy for union renewal in post‐Great Recession Spain, then there is still room for promoting deep coalition building between unions and novel forms of worker collectivism, as well as developing intersectional politics to reach non‐traditional membership groups.
